Hey all,

I just began with making pixel art, at the moment I am making a little Toad. But I stumbled upon a problem I can't solve: creating a curve. My first curve went well, but then I had to make an opposing curve. I tried a lot of different approaches but I cannot get it right. Could someone help me out?

The problem:
In the left red box is my first curve. Now I have to make a similar curve in the right box. The curve start at the right bottom and should end up at the top left corner.


Cheers

My result probably isn't perfect, and probably isn't the best way to do it.

Let's start by mirroring the first curve-



Clearly the problem is that the first curve only has to travel between the two nearest points, while the second curve needs to go between the two furthest points.



Here's the distance they're traveling. In the first line for every 5 pixels you go up, you go right 6 pixels. Looking at the second line, for every 11-12 pixels you go down, you only go right 5-6 pixels. The amount traveled to the right is about the same, but the amount traveled down is slightly over double.

So what I did was manually move each pixel column in the second curve down by one in relation to the previous column and then filled in the blanks.



As you can see my result is slightly off, but seen from a normal 100% view it looks pretty close.
